DISPOSABLE FORMWORK FOR MAKING VENTILATED LOOSE STONE FOUNDATION AND VENTILATED LOOSE STONE FOUNDATION COMPRISING SAID FORMWORK

摘要

A disposable formwork for making ventilated loose stone foundations, in particular for floors, slabs, storage and/or collection tanks, dispersion tanks, alveolar concrete beds, cavities and/or similar building structures is described. The disposable formwork comprises a body having a first substantially convex surface intended to receive at least one binding material casting, optionally concrete, and a second surface, facing the opposite side of the first surface, substantially concave and suitable for delimiting, at least partly, a cavity; at least one support element, in particular four, having at least one contact portion arranged to engage a bottom surface of a cavity of a building structure under construction and arranged to support the body according to a position spaced from the bottom surface of the cavity. The disposable formwork has at least one portion made of polystyrene. Preferably, the entire structure of the disposable formwork is advantageously made of polystyrene.
